Question 1:
F(x) and g(x) are like variables, just plug into the equation.
f(x) + g(x) = (x + 6) + (12x - 7)
x+6+12x-7 = 13x-1
Question 2: f(3) + g(-1)
You plug in the x-values into the equation, and then take the answer and add them together.
f(3) = 3+4
g(-1) = 12(-1)-6
f(3) = 7
g(-1) = -18
7 + (-18) = -11
Question 3:
This is similar to question 1, plug in the variables and simplify.
9x - (7x+3)
Remember to distribute the "-"
9x - 7x - 3
2x - 3
The strongest linear relationship of correlation coefficient is a -1 or 1.
According to the statement
we have given that the cases and the out of these we have to ensure that which case show the correlation coefficients is indicative of the strongest relationship between the two variables
So, For this purpose
The relationship of correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of two variables.
And according to the given cases
The strongest linear relationship is indicated by a correlation coefficient of -1 or 1.
The weakest linear relationship is indicated by a correlation coefficient equal to 0. A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.
So, The strongest linear relationship of correlation coefficient is a -1 or 1.

The answer is
6 boxes x 20 tiles/box = 120 tiles
Price was $95.94
$95.94/120Tiles = $.7995/Tile = ~ 80 cents per til
Answer:
31/50cm probably?
Edit:
Well stratch, that I don't know, I'm sorry.
